WASHING-MACHINE Specification of Letters Patent.

Application iiled April 28, 1905- Serial No. 257,951.

To all whom it may concern:

Be it known that we, FRANCIS BRUCKER and ABRAHAM L. STUMP, lcitizens ofthe United States, residing at Shelby, Ohio, have invented certain newand useful Improvements in Washing-Machines, of which the following is aspecification.

Our invention relates to improvements in washing-'machines of that typein which aA suitably-supported tub is rotated or oscillated by theoperator and the clothes are subjected to the action of a rubber heldwithin the tub against rotary movement.

We 'have aimed to improve the machine-in its various structural detailswith a view to increased simplicity, econom of manufacture, anddurability; and to t 's end the invention includes the various featuresof construction and arrangement of parts herein- Aafter described, andparticularly pointed out in the claims.

The invention is illustrated in the acco1n` panying drawings, in which-Figure l, is a sectional elevation. v Fig. 2 is a detail 'section online x of Fig. 1 Fig. 3 is a bottom view of the tub. Fig. 4 is amodiiication, and Fig. 5 is a detail view o the -hub and rocking arm.

I In the drawing the ordinal 1 designates the tub, which is rotatablymounted in the manner hereinafter specified upon the hub 2 of a stand orsupport. This hub 2 has two semicirculanrecesses or grooves 2"L and 2bin its under side, which cross each other at right angles and lie indifferent planes andare' adaptedl to receive the horizontal portions?,aand Sbof the supporting members or legs 3. These members are preferablformed of tubulax" sheet metal, and the orizontal portions Sa and 3b areheld in the recesses 2a and 2b by the lextension 4 of the post 9, whichpasses through openings in the parts 3a and 3b, where the crosseachother, and carries at its lower en a clamp'l-nut 5. The legs orsupporting members are 'tied together or braced.by a continuous rod ofwire or the like 6, passing through openings in the legs.

The rod 9 is encircled by a sleeve 10, which vpasses through the bottom1a of the tub, where itvdetachably engages a plate 8, prei'- erably by ascrew-threaded connection, as shown. "s Encircling the vsleeve above thebottom is a member or piece d, rabbeted out l to receive the inner endsof the rubldng-ribs '55 u, which have their outer ends seated in thegrooves or recesses ein the staves of the tub.

Above the piece d is placed a plate f, which is clamped in position byawasher g and screw-threaded collar h, threaded upon the sleeve 10, bywhich all of the aforesaid parts .I

may be securely clamped together land a water-tight joint effected. Therod 9 is reduced at its upper end, where it carries a bearing-ring 11,upon which'rests a series of balls 12. A cap 13 has aninwardly-extending'ilange 13a at its upper end adapted to rest upon thetops of the balls, while its lower end 13b is threaded to engage thesleeve 10. From .this construction it will be seen that the weight ofthe tub is supported bythe antifriction-bearing thus provided. at theupper end of the sleeve and may be freely rotated thereupon. j

In order to prevent any binding or friction between the sleeve 10 andspindle 9, at the lower -end a space is provided .between the annularflange 88L of the plate 8 and the spindie 9,*in which space is located aseries ot balls 8b, thesel being supported at the bottom by abearing-surface?, formed as an upward extension o'f the member 2.Encircling the hub 2 is a yoke 2d, which has a central opening larger.than the hub, as shown in 5.

A recess is formed inthe wall of said opening at one side, into whichprojects a rib 2e orrthe hub. An arm 2f projects from the opposite sideof the yoke, to Which arm is connected.

one end of a spring 2g, the other end of which engages a hook orprojection 1b, depending from .the bottom of the tub. By thisarrangement the tub is allowed a certain amount of free movement beforethe spring begins to act, making its operation easier.

The spindle 9 terminates a short distance below the top of the tub, andits reduced upper end 10a receives the upper end of a sleeve 19, whichis rigidly secured to said reduced neath the same it is yet heldagainstbeingrotated as the tub is oscillated. By this ar- IOO IIO

A intact throughout its entire surface, avoiding any openings throughwhich steam may escape or the necessity of packed joints to prevent theescape of steam.

Beneath the bottoni of the tub we provide pivotally secured in eyes 23h,carried by plates 23C, secured to the lower face of the tub-bottom. rIhebail is preferably of substantially V shape, and its central portion hasan angular portion 24, designed to be sprung over or into engagementwith the lower hoop of the tub, as shown. Thus when the tub is beingoscillated the bail rotates therewith and is out of the way. When,however, the clothes are pro erly washed and it is desired to hold thetub stationary, the bail may be released at its end, freed from the tub,and drop ed down into the position shown in dotted lines to engage oneof the angular supporting members. The tub will thus be securely heldagainst rotation while the wringer-board is being attached andthereafter braced, and 4thusexcessive strain removed from other parts.

In the modified form of stand we extend one of the members 3 outhorizontally to a point outside of the periphery of the tub,as shown at3, at which point it is provided with a T-coupling 3d, to one arm ofwhich is connected the leg portion 3e, while the other arm carries theupwardly-extending member 3f, which extends upward -slightly above thetop of the tub. A wringer-board 7 has a socket member 7al secured to oneend and designed to rotatably engage the upper end ofV this member 3f,being held against vertical displacement thereon by a collar 7b.

The opposite or free end .of the wringerboard carries a clamp 7 C,secured in place by bolt 7g. and having a rigid jaw 7d and an adjustablejaw 7e, capable of being adjusted and clamped in any desired position bya thumb-nut 7f. By this arrangement the wringer-board may be swung overand its clamp secured to theedge of the tub, thus serving. the doublepurpose of holding the tub stationary and the wringer-board in positionto have a wringer clamped thereto.

a bail 23, which has its angular bent ends 23a.

Having thus' described our invention, what we claim is- I 1. In awashing-machine, the combination with a rotary tuband stationary rubber,of a lstandor support comprising a hub having horizontal grooves orrecesses on its lower face, and supporting members clamped withinsaid'reeesses, substantially as described.

2. In a washing-machine, the combination with a rotary tub, of a standor support comprising a hub having open horizontal recesses or groovesin the bottom thereof of dill'erent depths, and supporting membershaving horizontal portions crossing each other and resting in saidgrooves or recesses with means for clamping them therein, substantiallyas described.

3.In combination, a stand or support, a vertical rod rigidly carriedthereby, a tub, a tubular sleeve passing through and secured centrallyto the bottom of the tub and encircling the rod, an antifriction-bearingbetween said sleeveand the upper portion of the rod, a second sleevesecured to the rod above said bearing and de ending outside of thefirst-named sleeve, an( a rubber having a sliding and non-rotatingconnection with the depending portion of said second-named sleeve,substantially as described.

4. In combination, a stand having a hub, a tub rotatablymounted on saidhub, a yoke pivotally held at one side of said hub and .having a limitedrocking movement thereon, an arm extending from the opposite side of'said yoke and a spring connection between said arm and the tub,substantially as described.

5. In combination, a stand having a hub, a tub rotatably mounted on thehub, a rib rojecting from one side of the hub, a yoke oosely encirclingthe hub and having a recess engaged by said rib, an arm projecting fromthe opposite side of said yoke and a spring connecting the arm with thetub, substantially as described.

In testimony whereof we a'llix our signatures in presence of twowitnesses.
